Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a grip portion of a nursing wheelchair.

[0002]

[Prior art]

 In general, a nursing-type wheelchair has a large wheel attached to the outside of a pair of left and right back pipes, and a grip joint provided at the tip of the back pipe with a grip portion having a grip at the tip. ing.

[0003] In the pair of left and right grip pipes, a joint is provided at the tip of the back pipe at an angle such that the grip portions are parallel to each other when standing, and are folded on the back pipe when not in use.

[0004]

[Problems to be solved by the invention]

 However, in the conventional nursing-type wheelchair, since the grip portions are parallel to each other when used, the distance between the caregiver and the grip portion is narrow, so that it is difficult to operate the wheelchair. However, there is a drawback in that the operation is difficult to apply and the tire is easily fatigued.

[0005] On the other hand, if the grip portions are opened in a V shape when the grip pipes are raised, a margin can be provided between the caregiver and the grip portions, and thus the operation of the wheelchair becomes easy. For example, operations such as curving a wheelchair can be performed smoothly.

However, if the grip portions are opened in a C-shape when the grip pipe is raised, a part of the grip portion protrudes outside the large wheel due to the structure of the wheelchair. When the grip pipe is folded, an inconvenience arises in that the grip portion contacts the large wheel and cannot be folded.

[0007]

[Means for solving the problems]

 In order to solve the above problems, in the present invention, a large wheel is mounted on the outside of a pair of left and right back pipes, and a folding joint provided at the tip of the back pipe has a grip portion at the tip. In the wheelchair with the pipes attached, the grip pipes are installed so that the grips of the pair of left and right back pipes open outward in a C-shape when standing, and the grips when the joint is folded. However, it proposes a wheelchair that is rotated inward so that it does not come into contact with the large wheels and is assembled to the back pipe.

[0008]

[Action]

 In the present invention, when the grip pipe is raised, it opens in the opposite direction to form a U-shape, so that there is a margin between the caregiver and the grip portion, which makes the operation of the wheelchair easy, for example, to curve the wheelchair. And the like can be performed smoothly.

In addition, in the present invention, since the above-mentioned joint is rotated inward and assembled to the back pipe, when the grip pipe is folded, it is folded inside the large wheel so that the grip does not come into contact with the large wheel. It is.

[0010] Therefore, in the present invention, when the grip pipe is raised, the grip portions are opened in a C-shape, but when the grip pipe is folded, the grip portion can be folded without contacting the large wheel.

[0011]

【Example】

 FIG. 1 shows a wheelchair according to the present invention. The body frame of the wheelchair has a pair of front pipes 1, 1 and leg pipes 2, similarly to a conventional wheelchair. 2, the base pipes 3, 3 and the back pipes 4, 4 are connected by a cross rod 5, and a seat 6 is stretched between the front pipes 1, 1 and the back pipes 4, 4; Is provided with a backrest portion 7, a legrest 8 is provided between the legs 2 and 2, and a footrest 9 is provided at the tip thereof.

A stem 10 is provided below the front pipe 1, and a caster wheel 12 is provided at a lower end of the stem 10 via a yoke 11. A large wheel 13 is pivotally mounted on the outside of the back pipe 4. Be worn.

On the other hand, a grip pipe 15 having a grip portion 14 formed by bending the distal end of the back pipe 4 downward is pivotally mounted on a joint 16 provided at the distal end of the back pipe 4.

The joint 16 includes a base portion 17 provided at the rear end of the grip pipe 15 and a receiving portion 18 provided at the distal end of the back pipe 4. At 19 is attached.

A stopper rod 20 penetrates the base end 17, an engaging hole 21 is provided in the receiving part 18, and an operation lever 22 is loosely fitted in the base of the stopper rod 20, and the The base of the lever 22 is attached to the shaft attaching portion 19 with a spring member (not shown) interposed therebetween so that the stopper rod 20 always projects from the base end 17 by the urging of the spring member. is there.

In the present invention, the grip pipes 15, 15 are installed with respect to the back pipes 4, 4 so that the grip portions 14, 14 open outward from each other when they stand up, forming a C-shape.

The joints 16, 16 are rotated slightly inward so that the grip portions 14, 14 do not come into contact with the large wheels 13, 13 when the grip pipes 15, 15 are folded (about 15 degrees in a general wheelchair). ), And assemble them to the back pipes 4 and 4.

In the above configuration, when the grip pipes 15, 15 are raised with respect to the back pipes 4, 4 when the wheelchair is used, the stopper rod 20 is engaged with the hole 21, so that the grip portions 14, 14 are It is fixed in a C shape.

As a result, a margin is provided between the side of the caregiver and the grips 14, 14, so that force is easily applied to the grips 14, 14, and the operation of the wheelchair is facilitated. The operation such as the operation can be performed smoothly.

When the grip portion 14 is folded, the operation lever 22 is pulled forward to release the engagement between the stopper-rod 20 and the hole 21 and the grip pipe 15 is tilted forward. The grip portion 14 is folded through the inside of the large wheel 13 without being in contact with the large wheel 13 because the 16 is rotated slightly inward and is assembled to the back pipe 4.

[0021]

[Effect of the invention]

 In short, according to the present invention, when a so-called nursing-type wheelchair is used, a pair of left and right grips can be opened and fixed in a C-shape, so that force is easily applied to the grips and the caregiver becomes tired. It is difficult, and there is ample space between the caregiver's side and the grip, which makes it easy to operate the wheelchair, and the grip pipe can be folded without the grip abutting on the large wheels.
